Terms in these criteria, in plain language(10)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Bilirubin

A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.

Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.

ALT and AST (liver enzymes)

Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.

Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.

ULN (upper limit of normal)

The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.

“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

What researchers measure

Primary outcomes

  1. Percent of Participants With Worst Itch Numeric Rating Scale (WI-NRS) 4-point Responder Rate at Week 10

    During the study, WI-NRS assessments were reported by the participant via eDiary once daily from screening/mid-screening visit through the follow-up visit. The Itch NRS is a validated, self reported, instrument for measurement of itch intensity and participants were asked to rate the intensity of their itch on an 11- point scale ranging from 0 (no itch) to 10 (worst itch imaginable); higher scores indicated greater itch intensity. A participant was a 4-point responder if their change from baseline is ≤ -4 (i.e. a decrease of at least 4).

    Time frame: At Week 10

  5. Change From Baseline in Dermatology Life Quality Index (DLQI) to Week 10

    Dermatology Life Quality Index (DLQI) is a dermatology specific quality of life (QoL) instrument designed to assess the impact of the skin disease on a participant's QoL over the prior week. It is a ten item questionnaire that assesses overall QoL and six aspects that may affect QoL (symptoms and feelings, daily activities, leisure, work or school performance, personal relationships, and treatment). The DLQI questions are rated by the participant as 0 (not at all) to 3 (very much). Scores range from 0 to 30 with higher scores indicating poor QoL.).

    Time frame: At Week 10

  6. Change From Baseline in DLQI Question 1 to Week 10

    Dermatology Life Quality Index (DLQI) is a dermatology specific quality of life (QoL) instrument designed to assess the impact of the skin disease on a participant's QoL over the prior week. It is a ten item questionnaire that assesses overall QoL and six aspects that may affect QoL (symptoms and feelings, daily activities, leisure, work or school performance, personal relationships, and treatment).

    Time frame: At Week 10

  7. Change From Baseline in Investigator's Global Assessment of Prurigo Nodularis Stage (IGA PN-S) to Weeks 2, 4, and 10

    The IGA PN-S is an instrument used to assess the overall number and thickness of PN lesions at a given time point, as determined by the investigator. It consists of a 5-point scale ranging from 0 (clear) to 4 (severe). Higher scores indicate severe prurigo nodularis.

    Time frame: At Weeks 2, 4 and 10

  8. Change From Baseline in Investigator's Global Assessment of Prurigo Nodularis Activity (IGA PN-A) to Weeks 2, 4, and 10

    The IGA PN-A is an instrument used to assess the overall activity of PN lesions at a given time point, as determined by the investigator. It consists of a 5-point scale ranging from 0 (clear) to 4 (severe). Higher scores indicate severe prurigo nodularis.

    Time frame: At Weeks 2, 4, and 10

  9. Number of Participants With Treatment-emergent Adverse Events and Serious Adverse Events (SAEs)

    Adverse events (AEs) and serious adverse events (SAEs) were recorded from the first study drug administration through the follow-up visit. Severity of all AEs were graded using the National Cancer Institute Common Terminology Criteria for Adverse Events v4.03. During the period between informed consent and first study drug dose, only SAEs caused by a protocol-mandated intervention were collected.

    Time frame: From screening until the Follow-up (F/U) visit which occurred 35 days (+ 7 days) after the Week 10 visit or the last dose of study drug for participants who discontinued study drug early

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Aug 2018 to primary completion in Jan 2020, 16 months.

Results were first posted in Oct 2020, 9 months after primary completion.

Of 42 industry-sponsored phase 3 interventional studies under Pruritus, half reached primary completion within 19 months of starting (the median), counting those still running; a quarter within 12 and three quarters within 26. This study's 16 months is below that.

Counting every sponsor, half of 48 studies reached it within 19 months; a quarter within 12 and three quarters within 29.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 20, 2021, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
